PNEUMATIC CLEANER OR SUCTION TOOL.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed June 5, 1916, Serial No. 101,696. Renewed June 11, 1921. Serial No. 476,967.

T 0 all whom it may concern:

Be it known that I, DANIEL; B. RnrLooLn, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Pneumatic Cleaner or Suction Tools, of which the following is a specification.

This. invention relates, specially, to pneumatic cleaner or suction tools, such as are attached to the ends of pipes used in connection with stationary or portable pneumatic cleaning machines, for removing dust from more or less uneven surfaces. More generally it relates to applying a fluid in motion to a useful purpose.

The objects of the invention are to improve the form, increasethe efficiency, and render such tools less liable to injure furniture; to improve their means of attachment, and kindred objects.

To these ends the invention consists of the construction and arrangement set forth herein and illustrated in the accompanying drawing, in which:

Fig. 1 is an underside plan view of a tool embodying my invention.

2 is a side view of same showing a part broken away to illustrate structure.

Fig. 3 is a shank end view of the tool with brush removed.

Fig. 4 is a perspective view of the re movable brush used in the tool.

Fig. 5 shows the device as attached to a fiat end of a suction pipe.

Fig. 6 illustrates a tool in use when applied to the end of a round suction pipe.

Similar characters of refernce denote like parts in the several views.

Referring to the drawing, the tool is shown as consisting essentially of a cavitous body having a shank 1 connected by a throat portion 1 to a mouth portion 2 having a circumferential lip 3, and with an interior annular flange or bead 4:. A brush 5 is made to fit into said mouth. This brush is formed with an open center to permit the passage of air and has a peripheral groove 6 extending around its body, said groove adapted to be engaged with the bead in the mouth of the shank member so as to be securely held in position.

The brush face may be provided with bristles, any of their equivalents: or with felt, or other friction material. The brush body is made of hard material such as wood, gutta peroha, or fibre, but the body memher is made of resilient elastic material such as rubber, and is adapted to be drawn tightly over the brush inserted in its mouth; and also to have its shank end drawn tightly over the suction pipe with which it is to be used. A lip 8 on the shank serves to make it more rigid. The shank by reason of its elasticity may be drawn over a flattened end 9 of a suction pipe or over a round end as 10 shown in Fig. 6.

The operation is now readily understood. Should the brush, which may be' of any desired stiffness, getclogged or matted, it is slipped out of the mouth and by inverting it, the clogging material is readily sucked out by the end of the pipe on which the device is used.

\Vhen cleaning cushions or bric-a-brac the soft body of the shank member may be allowed to strike delicate surfaces without injury. The whole is light in weight, conforms to angular positions by its flexibility, is readily applicable to different shaped pipes, and therefore attains the objects set forth in a manner I verily believe to be novel. The form may be varied from that shown and any size used; as for instance the brush member may be faced with felt, or an abrasive, and may be made oval or oblong and the shank may extend straight or at any desired angle from the mouth, instead of at right angles as I have shown.

What I claim is:

1. In a suction tool, a-cavitary body of resilient elastic material, said body comprising a shank portion and a mouth portion joined and communicating through a throat portion; in combination with a ring shaped open center brush, having a circumferential groove, insertable into said mouth portion, and an internal annular bead in said mouth portion arranged to engage claspingly with said groove.

2. In a suction tool, an elastic resilient shanked hollow body member having a throated interior, a mouth portion communicating therewith, a circumferential lip on said mouth, an open centered brush insertable into said mouth and said lip adapted to be stretched and drawn over the body of said brush.

3. In a suction tool, the combination with a resilient elastic interiorly throated memher having an elastic open shank and a mouth, communicating therewith; of a ring shaped open center brush, said brush and the throated member having means for'remining said brush within said mouth in operable position.

4. A cleaning tool comprising a resilient elastic interiorly throated member, having an elastic open shank and a mouth communieating therewith, an open centered brush member adapted to be inserted into said moufih, and means Within the tln'oated memher for retzunlng said brush member within 10 sa d mouth, 1n operable positlon.
